I build things. Bicycles, computers, websites, guitars, cars, motorcycles, sound sytems... lots of things.

Do you have evidence or citations that nothing can be absolute zero? Or are you just asserting it? Note that saying 'we can't get to absolute zero' is different than 'no particle anywhere, at any time, can be at absolute zero.'

But the existence of one time dimension doesn't cause all sorts of paradoxes, or tell us we cannot measure things, or necessitate that we abandon classical mechanics in all circumstances. You seem to be comparing my question with just asking random what ifs, but I just want to challenge the implicit certitude that the HUP/wavefunction model asserts unknowability across all particles, everywhere, at all times under all conditions, regardless of technology advances - with the only justification so far of "well, it works for the limited amount of things we tried" - insufficient for the claim.

But then why can't we just say 'HUP is only for particles not at absolute zero'? It seems like violating it is 'not an option', even as above - so an electron falls into the nucleus. It has a measurable position and momentum. Why does HUP have to hold so strongly that we instead are comfortable with 'that particle must always have energy'?

(I'm not trying to prove it wrong, or stating that it is, I'm asking if it can be false and if so, why it's not treated as such)

We can't prove Zeus doesn't exist, yet we don't accept his existence because of this. An idea shouldn't have to be 'debunked' to have a healthy amount of doubt in it, yet the wave formulation representing all particles, everywhere, at all times and locations seems to be presented 'beyond doubt' - so why is it stated with such certainty about unknowability and when challenged, the opposition gives in without so much as a mention?

This was rather helpful, so I appreciate it. I'm still just having difficulty wrestling with unknowability in relation to this; for example if we ever found a way to arrest a particle completely; we'd know it's position and momentum (0) both at the same time, and while it violated HUP, it could just be said 'this particle cannot be represented by a wavefunction.' The reach of the HUP seems to include this though, with no provisions, and just be accepted so OBVIOUSLY you can't stop a particle. Would we just say the particle is classical in that instance?

No, do you have one that you recommend?

So just accept it as true until it's proven wrong? Sounds like the Flying Spaghetti Monster argument. And why does it need to be 100% right or completely wrong? Special relativity didn't 'prove Newton wrong,' it just improved the accuracy of the equations when measuring things Newton could not possibly have measured.

It's a mathematical fact IF the particle can indeed be wholly represented by that specific function, right? So in the entanglement experiment, perhaps that function does not represent the state of TWO entangled particles? Maybe we have entanglement wrong, or maybe that function does not represent particles in certain conditions? Why are these possibilities not even discussed?

Not really. Bombarding it with photons are distinct events; surrounding it by a machine that is sensitive to the gravitation inside of it would only exert the same gravity that any other matter around it would, and if done as stated in my hypothetical, would not alter the position or momentum in any way once the particle has settled inside the machine.

Then why is there not a third option in the EPR Paradox as quoted above, in the entanglement setup, you just get to know the momentum of particle A and position of particle B, thereby beating the HUP? It's just taken off the table as an option, and I'm not sure why?

I want to know what evidence there is to support this, even in the case of such a hypothetical machine.

I think that's just the observer effect, described in another answer, and I can beat that by hypothesyzing a future race that has developed a gravitational particle-position-and-momentum sensor machine, which does not use photons or interact with the particle in any way that would change the position or momentum (a read only sensor). Even in this case, the HUP says they CANNOT be known simultaneously.

So how do we know that all particles have a non-commuting relationship, always and forever, under all conditions, even the ones we aren't able to measure or with technology or knowledge we don't yet possess?

How about saying x and p are a pair of fourier transforms USUALLY, but not in certain circumstances such as {inside a black hole, at absolute zero, under certain entanglement experiments, in a zero rest energy universe, etc.} How do we know that because QM is right USUALLY or from what we can observe, that it is right ALWAYS and FOREVER?

comment What would be likely to completely stop a subatomic particle assuming it was possible?
I don't. One of the claims I don't make is that it is impossible that my grandfather was not a sperm in a lab tube. The claim of the uncertainty principle is that it is true with absolute certainty, everywhere, at all times and under all conditions; even ones we haven't observed (like a particle at absolute zero). It would be wise to doubt anyone that claims certainty about the birth of their grand grand fathers. Why is it not wise to doubt the uncertainty principle's claims to perfect adherence, everywhere at all times?
